Objective To study the toxicity and mechanism of fullerene(C_(60))on human embryo liver L-02 cells.Methods L-02 cells were exposed to C_(60)suspension of different concentrations(0.00,1.25,2.50,5.00,10.00,20.00 and 40.00?g/ml)for 24 h,then the content of GSH and the activity of LDH,SOD were determined,the viability of cells with/without NAC was also compared.Results Compared to the control group,the viability of cells exposed to 1.25,2.50,5.00,10.00,20.00 and 40.00?g/ml C_(60)suspension decreased in a dose-dependent manner,and the differences were significant(P

Studies in recent years have demonstrated that stromal cell-derived factor-1 SDF-1/CXCR4 axis plays an important role in the process of angiogenesis. The expression of SDF-1 in ischemic tissue increases during cerebral ischemia. It binds to CXCR4 receptor on the surface of endothelial progenitor cells EPCs, and thus promotes bone marrow-derived EPC mobilization, proliferation, and migration to the ischemic areas and homing. EPCs differentiate into mature endothelial cells in the ischemic region, promote the formation of new blood vessels, and thus irrlprove the blood supply to ischemic tissue. This article reviews the effect of SDF-1/CXCR4 axis in the treatment of cerebral ischemia with EPCs.

The prevention,diagnosis,treatment,and recovery of serious diseases can't be well done without the family's proper awareness and wisdom of choices.The target population of the prevention and control of serious diseases and health education should take a family as the basic unit and let the family become the first line of defense against the serious diseases.The idea and practice of Healthy Family has established a strong bond between the Healthy China strategy and the broad masses of the people,helping achieve the bottom-up interconnection and promoting Healthy China 2030 to benefit all.

Objective To explore the effect of combined use of schizophrenia combined with psychological intervention on benzene exposure to workers. Methods A total of 106 workers were randomly divided into observation group and control group. The 106 workers were randomly divided into observation group and control group. The workers were randomly divided into observation group and control group. 53 patients were given the observation group combined with the psychological intervention, given the control group placebo, 3 months after the intervention to compare the two groups of workers blood parameters, oxidation-antioxidant indicators and genetic damage indicators. Results The WBC and PLT were significantly increased after treatment (P<0.05 or P<0.01), while MDA and MN were significantly decreased (P<0.05). Conclusion Leucosonurn has some protective effects on blood system damage, oxidative damage and cytogenetic damage caused by exposure to benzene, and the combination of psychological intervention is beneficial to the early prevention of benzene poisoning.

Tumor recurrence and drug resistance impact patients'therapeutic effect and prognosis seriously.In recent years,it has been found that epigenetic changes are involved in drug resistance.DNA methylation is one of the ways of epigenetic.DNA methylation of drug metabolism enzyme gene can affect gene's expression,leading to drug resistance.Methotrexate(MTX),a folic acid antagonist,is the most widely used drug in the treatment of malignant tumors,such as leukemia,osteosarcoma,head and neck cancer,and so on.Reduced folate carrier(RFC) is the main transporter cartier of MTX,and gene methylation is related to tumor cells'resistance to MTX.This paper reviews the role of RFC,relation of RFC methylation and methotrexate resistance and the factors of RFC methylation.

Objective To research the important of prenatal diagnosis and effect of intervention to fetal hydrothorax. Methods The cases of fetal hydrothorax (n=5) were obtained from the Shengjing Hospital,China Medical University between December 2014 and May 2015. All pregnancies were uncomplicated, excluded congenital organic and chromosomal abnormalities during prenatal diagnosis and with a 37 average gestational weeks. The case 1, 2, 4 were unilateral hydrothorax and the case 3, 5 were bilateral. We performed an antenatal thracocentesis to case 1, 2, 3. In case1, the hydrothorax increased rapidly after 5 days, and the patient underwent a cesarean section and ex utero intrapartum treatment (EXIT);in case 2, the fetal heart rate was decreased to 40-50 bpm suddenly during thracocentesis, and we performed an emergent cesarean section and EXIT for the patient; in case 3, the patient underwent thracocentesis and a meanwhile cesarean section and EXIT procedure. We performed a conservative management to case 4, 5, the hydrothorax resolved spontaneously during the pregnancy and after birth, both patients underwent cesarean section. Results All fetuses were survived, the neonates of case 1, 2 and 3 underwent assited mechanical ventilation, thoracic close drainage, then discharged after hydrothorax resolved and feeding tolerance;in case 4, there was no respiratory distress and hospital treatment;in case 5, the neonate underwent assited mechanical ventilation and conservative management, the hydrothorax has resolved gradually. Conclusions The prenatal diagnosis and antenatal intervention (thracocentesis) may play an important role in fetal hydrothorax treatment. In clinical, we should choose different plan according to the gestation weeks and classification of hydrothorax of the patient.

Objective To investigate the status of stroke patients′continuous rehabilitation care and it′s influencing factors in the community. Methods Questionnaires were used to investigate 174 stroke patients from 6 communities of Zhengzhou. Results The implementation of continuous care was not satisfactory. Occupation, medical payment method and medical resource utilization were important predicting factors. Conclusions In order to promote continuous rehabilitation care, the health resources should be fully used, the payment methods of the patients should be improved, and the occupational characteristics should be considered.

Objective To analyze and study the relationship between plasma adhesion molecules,free amino acids and ovarian cancer.Methods A total of 67 patients with ovarian cancer in our hospital during the time of March 2015 to May 2016 were selected as the observation group,and 67 healthy women at the same time were selected as the control group.The plasma adhesion molecules and free amino acids levels of two groups were detected and compared,The detection levels of observation group with different stages and degree of differentiation of ovarian cancers were compared.The relationship between plasma adhesion molecules,free amino acids and ovarian cancer were analyzed by the Logistic analysis.Results The plasma adhesion molecules levels of observation group were all higher than those of control group (P ＜ 0.05),the plasma free amino acids levels were all lower than those of control group (P ＜ 0.05),and the detection levels of observation group with different stages and degree of differentiation of ovarian cancer plasma adhesion molecules and free amino acid levels had significant differences (P ＜ 0.05).The Logistic analysis showed that the plasma adhesion molecules and free amino acids had close relationship to the ovarian cancer (all P ＜ 0.05).Conclusions The plasma adhesion molecules and free amino acids of the patients with ovarian cancer show abnormal expression state,and the expression levels of patients with different stages and degree of differentiation of ovarian cancer have certain differences,so the detection value of those indexes in the patients with ovarian cancer is higher.

Objective At present study,we sought to further define the significance of endoscopic and pathological findings in the diagnosis of acute intestinal GVHD.Methods The clinical、endoscopic and pathological data in 23 patients with proven acute intestinal GVHD were retrospectively reviewed.Results The endoscopic features of the ileum and colon varied from being grossly normal、loss of vascular markings、diffuse mucosal erythema、edema and friability to erosion、ulceration、mucosal sloughing and bleeding.Pathological findings included crypt epithelial cell apoptosis and dropout、crypt destruction and variable lymphocytic infiltration of epithelium and lamina propria.Conclusion Endoscopic and pathological evaluation of the ileum and colon can be used to diagnose acute intestinal GVHD.Endoscopy may play a significant role in establishing early diagnosis for acute intestinal GVHD in patients following allogeneic BMT,but pathological evaluation of the ileal and colonic mucosa is needed to confirm the final diagnosis.
